LUBBICATOR.

Specification of Letters Patent.

Patented June 17, 1913.

Application led August 14, 11912. Seria-IN1?. 715,100.

To all "wha/1t t may concern.'

Be it known that I, GEORGE F. EDGINGTON,

a citizen of the United States, residing at engaging a nipple carried by the hub and through which the lubricant is to be directed, a screw actuated plunger being mounted in the moveble container and actuated to supply the lubricant and retain the container closely to the nipple simultaneously.l

Wit-h the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without depart-ing from the spirit of the invention.`

In the drawings Figure 1 is a longitudinal sectional view through the complet-e lubricator and hubv nipple. Fig. 2 is a top plan view thereof. Fig. 3 is -a vertical longitudinal sectional view through the hub nipple and the adjacent portion of the lubricator and container. Fig. 4 is a longitudinal sectional view through a vehicle hub and axle with the lubricator in operative relation thereto.

Referring to the drawings, the numeral 1 designates a pipe which is connected to supply lubricant to the axle A and has its upper terminal or nipple 2 disposed to project between the spokes S ofA the wheel, the outer end of the same being sealed by any form of cap.

The supporting frame for the lubricator is provided with a V-shaped portion having the reduced spaced terminals 4 which are adapted to t astride of the nipple, as clearly IshownV in Fig. 4, and the diverging arms'3, which terminate in the parallel and spaced arms 5 and 5 which provide a supporting means 'for the stationary open ended me-` tallic cylinder 6 which'is connected to ther arms 5 and 5 by mea-ns of the rivets 7.

Mounted removably and slidably within the stationary cylinder 6 is the cylindrical portion of the lubricant container 8 which is provided With the' funnel-shaped end 9.

terminating in the lubricant directing or eduction spout 10. This spout 10 is mounted so as to be placed in engagement with the extreme outer end of the nipple 2 and concentricall ofthe sleeve 11 which is connected within the frame by means of the rivets 12.

Bymeans of the hinge member 13, the bridging plate 14 is connected to the terminal of the arm 5, the same being provided with an aperture 15 adapted to fit over the stud or coacting latch member 17 formed A a pivoted g1n g meinposltion as *upon the extreme end of arm 5 latch 16 being carried by the brid ber 14 to lock the same in the shown in Fig. 1.

. The threaded stem 18 is threaded through the brldging plate 14 and is provided with the operating handle 19, while upon its reduced end 20 is rotatably mounted-the conical disk 21, the head 22 and the Washer 23 providlng a means for retaining the disk 21 relatively to the screw 18. Secured to the conical face of the disk 21 is a flexible covering 24 whose peripheral rim 25 engages the inner wall of the container 8 to provide the rotation of the stem 18 in the opposite direction retracting the plunger 21 and at the same time also moving thecontainer 8 in the same direction and removing the nozzle 10 from engagement with the nipple 10 into close engagement with the nipple 2, t

2. By this means the greater the pressure exerted upon the stem 18 and plunger 21, the greater pressure will be exerted to hold the container in close engagement with the nipple 2, thus permitting the better supplying of a heavy grease through the pipe 1 to the axle. In fact the pressure may besuch as to force the older lubricant Within the hub and around the axle out ofv the respec- Y \Vhen it desired to 'refill the container 8, the screw V18 is rotated togrei'nove the plunger 21 exteri'orly of the containerV 8, at

-which 'time the latch *16 is manipulatedl to permit the bridging plate 14 to be .swung outwardly and carry with it the plunger21. The container 8 may now be removed from the cylindrical carrier to be -fi1led, after which the same is replaced :,nd thebridging plate 14 is again fastened inplace by means ofthe latch 16..

What is claimed is: f A lubricator, including'. av supporting frame, having ja -YShaped nipple engaging portion terminating 'in two parallel and s aced arms, one ofsaid arms being provided with' a hinging member, and the opposite arm being provided with a latch member, an open ended cylinder disposed between the parallel arms and terminatin at a point adjacent the junction of the Y- Eliapcd portion with the parallelarms of the frame, the opposite end of the cylinder terminating at a point within the terminals' of 'the parallel arms, a lubricant container having a cylindrical body portion open at one end and carrying a funnel shaped eduction portion at the Opposite end,'the cylindrical portion being slidably mountedwithin and of lesser lengththan the first mentioned cylinder, the

outlet end ofthe funnel-portion being prn- 'jected between the reduced portion of the Y-shaped portion .of the frame, a bridging l arm, the central portion` of the bridging member being provided with a threaded aperturev therethrough, a lhandle actuated screw mounted in said aperture for movement therethrough, the lower end of said screw being reduced, and a cone-shaped plunger rotatably mounted upon the lower end of the screw and carried by thescrew,

'plate havinga v`ligiiiging member coacting said plunger being disposed for movement into and ont of the cylindrical body portion ofthe lubricant container'.

In testimony that I claim the foregoing as my own, I havehereto alixed my signature in the presence of two witnesses.
